Exceptional poles of local $L$-functions for $GSp(4)$ with respect to split Bessel models

Rainer Weissauer

Piateskii-Shapiro defined local $L$-factors $L^{PS}(s,\Pi ,\Lambda )$ attached to irreducible admissible representations $\Pi$ of the group $GSp(4)$ over local fields and Bessel models of $\Pi$…
